Passenger wakes up alone on locked plane

(USA TODAY) -- A man who dozed off on a flight from Louisiana, awoke to find himself cold and alone on a locked plane.

Tom Wagner was on his way to visit his sister in California. He decided to take a nap before his layover in Houston, and continued to sleep as the plane landed and the other passengers disembarked at George Bush Intercontinental Airport. Somehow the flight crew did not notice the sleeping Wagner and left him on board as they locked up the plane, the ABC affiliate KTRK reports.

Wagner found himself sitting in the dark on the empty plane and discovered he had been locked in. Luckily, his phone was working and he was able to call his girlfriend, who then contacted United Airlines to say Wagner was trapped on one of their flights.
